摘要
实现形式是ＳＴＥＰ标准的主要内容之一，本文通过分析ＥＸＰＲＥＳＳ语句结构特点，对ＥＸＰＲＥＳＳ数据模式在关系数据库上的实现进行了研究，提出了ＳＴＥＰ集成系统的实现框架，并定义了ＥＸＰＲＥＳＳ数据模式向关系模式转换的规则和方法，为ＳＴＥＰ产品数据库在关系数据库上的实现创造了条件。
Implementation method is one of key part of STEP standard (ISO10303). This paper stu dies the implementation method of EXPRESS schema in a relational database by analyzing the structure of EXPRESS language. The implementation architecture of STEP based integration system is defined and the rules and methods of transforming the EXPRESS schema into relational schema are also defined. This method presents a feasible way to approach the STEP product database in a relational database.
